Patrick Crozier, a libertarian who has been active in the Libertarian Alliance for many years, has set up InstaPatrick, a wiki where he catalogues his thoughts and opinions on many issues. You can see a listing of all the pages in his wiki here.
Pages like “Why British rail privatisation failed” or “Against taxation” allow Patrick not only a resource to which he can refer others in the course of online conversation, but also can be found by people using search engines to find information on these issues. (It also makes for addictive reading for someone like me, who has come to similar views relatively recently. It is much handier than pestering longtime libertarians like Antoine Clarke and Brian Micklethwait about every question that crosses my mind.)
I have been thinking about how the LA could use wikis to help spread its wisdom and gain influence. For starters, each page about a particular issue could also link to all related LA papers; this would be incredibly useful to journalists and students, among others. If you have your own ideas, feel free to share them in the comments.
